Hello, a little more than a week ago I had kissed a stranger, not thinking about the risk of contracting herpes. About two days later on the upper left side of my lip it began to feel painful, not tingly as a herpes outbreak is explained as, but felt as if a pimple was forming. No cold sore or blister had formed in the area, but now I have a little red area. Does this sound like herpes or am I just freaking myself out?
